Frequently Asked Questions

  • What's the difference between regular and decorative concrete?

    Regular concrete provides a smooth, functional surface, while decorative concrete adds visual interest through stamping, coloring, or texturing. Decorative options mimic natural stone, brick, or custom patterns and include protective coatings for durability. At McKnight Construction LLC, we help Corvallis homeowners choose finishes that match their style and withstand Oregon's wet climate.

  • How does stamped concrete hold up in Oregon weather?

    Stamped concrete performs well in Oregon's rainy climate when installed with proper grading, reinforcement, and protective sealers. These techniques prevent moisture damage and surface cracking over time. McKnight Construction LLC uses moisture-resistant finishes ideal for Corvallis and coastal areas like Newport and Depoe Bay.

  • When should you replace old concrete surfaces?

    Replace concrete when you see widespread cracking, uneven settling, or surface deterioration that affects safety or drainage. Minor cracks can sometimes be repaired, but structural issues usually require full replacement. At McKnight Construction LLC, we assess aging driveways, walkways, and patios throughout the Corvallis area.

  • What affects the cost of a decorative concrete patio?

    Cost depends on surface area, pattern complexity, color choices, and the number of custom details like borders or textures. Protective sealing and site preparation also influence pricing. McKnight Construction LLC provides free estimates to help homeowners in Corvallis understand options and budget accurately.

  • How do you prepare a site for concrete installation?

    Proper preparation includes grading the soil, compacting the base, and installing reinforcement like rebar or mesh. This foundation prevents cracking and ensures long-term stability. McKnight Construction LLC uses precision tools and proven techniques for driveways, patios, and foundations across Corvallis and surrounding areas.

  • What's the biggest mistake homeowners make with decorative concrete?

    Skipping or delaying sealer application is the most common error. Without protective coatings, decorative surfaces absorb moisture, stain easily, and fade faster. At McKnight Construction LLC, we apply quality sealers during installation to protect patios and walkways from Oregon's rain and seasonal wear.

  • Can you add decorative concrete to an existing patio?

    Yes, if the existing surface is structurally sound and properly prepared. Overlays or resurfacing techniques allow stamped or textured finishes on older concrete. McKnight Construction LLC evaluates current conditions and recommends the best approach for homeowners in Corvallis and nearby communities.

  • How long does decorative concrete last?

    With proper installation and regular sealing, decorative concrete can last 20 to 30 years or more. Durability depends on climate, usage, and maintenance like resealing every few years. McKnight Construction LLC builds long-lasting decorative surfaces suited to Oregon's coastal and valley conditions.

  • What materials work best for concrete in coastal areas?

    Moisture-resistant mixes, proper reinforcement, and high-quality sealers are essential in coastal climates with heavy rain and salt exposure. These materials prevent cracking, staining, and surface degradation. At McKnight Construction LLC, we serve Newport, Depoe Bay, and Waldport with techniques designed for durability near the coast.

  • Why is reinforcement important in concrete slabs?

    Reinforcement like rebar or wire mesh distributes weight and prevents cracking from settling or heavy loads. It's especially critical for driveways, foundations, and high-traffic areas. McKnight Construction LLC uses code-compliant reinforcement methods for safe, long-lasting concrete work throughout Corvallis and surrounding cities.
